Application october 27, 1933, serial Ndfctsse 2 Claims. (01212-53) This invention relates tothe supply of fresh web rolls to the reels or other supports on which they are carried, said web vrolls being used to supply the webs to a printing press.

The principal object of the invention is tol pro-vide means whereby the fresh roll can be introduced into a space below the press in any convenient manner, such as rolling it along the floor, where it will be'out of position to engage the machinery, and to: lift the roll in a simple and convenient manner into substantially the exact position for application to the reel or other support on which it is to be mounted.

Other objects are to provide a convenient relationship between the position of the part of the reel which is to receive the fresh roll and the preliminary supportfor the fresh roll directly below it and to provide means for accomplishing the above mentioned results in a printing press plant in which there is insufficient room at the side of the press to permit the rolls to be brought in in the ordinary manner.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which Fig. 1 is a diagrammatic side view of a printing press with the present invention shown in its proper relation thereto, and

Fig. 2 is an end view of the same with the printing press omitted and with some of the longitudinal supports in section.

It is customary to bring the web rolls in on the same iioor level as that on which the reels are mounted and the rolls have to be brought in between the reels for loading them. This requires a certain amount of room at the side of the press to permit the rolls to be brought in in this manner and this invention relates to a case in which that room is not suiiicient.

According to this invention the parts are so arranged that the rolls are brought into the position on a floor, from which they are to be taken directly to the reel, on a level beneath the oor of the reel and far enough below the reel so that the rolls can be brought into the position just mentioned in any convenient manner, such as rolling them underneath the reels. lSimple means is provided for then transferring the rolls from the position just mentioned to the position which they are to occupy on the reel.

In the drawings an ordinary press Ill is indicated diagrammatically with reels II arranged beneath the bottom of the press for mounting the rolls which are to feed the press with the webs of paper, as indicated. Below the level of the reels is a space in which the fresh rolls I2 can be rolled around or transported at will and located in the desired position.

Each roll is rolled onto a cradle I3 which has 5 two ends I4, each provided with an integral nut I5 arranged vertically. These cradles are, oi.' course, low Vand can be set with their tops at the bottom floor level, if desired. On the frame I6 of this part of the device is a bracket I'I at each 10 side having a vertical opening therethrough forV receiving the end of a screw I8. This screw passes through the nut in each case and extends to the top of the reel part of the frame I6. This screw is operated by a motor I9 through a 15 chain 20 and a worm wheel 2l, the worm wheel being mounted on the screw to cause the screw to rotate when the motor operates. The worm that operates the worm wheel 2l is mounted on a shaft 22 which extends across the machine where similar connections are provided for the corresponding screw I8 on the other side. Therefore, these two screws will always operate simultaneously and synchronously. The two ends of the cradle I3 will be raised or lowered alike.

Of course, the motor is provided with any usual control so that it can be operated through a part of a revolution at a time for jogging the cradle up and down slightly when the roll is practically in loading position. In this way the reel can be turned in the usual way to bring the chucks thereof substantially into the proper position to receive the roll and the roll can be moved up and down to locate it accurately with respect thereto. l

If the roll I 2 is mounted xedly in one position on the cradle it is necessary to bring the reel exactly to a predetermined position to receive the roll. However, I prefer to make the arcuate depression 23 in the top of the cradle for receiving the roll of slightly greater radius than the largest roll so that a slight rolling motion is permitted to the roll on the supporting cradle. In this way, although the reel has to be brought to a definite position, a slight error can be obviated by rolling the roll in its cradle by hand. 'Iransverse rollers are provided on cradle I3 permitting end motion of the roll thereon to facihtate in loading the roll in the reel.

It is to be observed that the floor 24 of the reel room or compartment is provided with an opening 25 therethrough for receiving the screws I8 and the roll I2. The reel is turned to a point at which the chucks for the new roll are substantially in the plane of the screws I8.

It will be seen therefore that the necessity of rolling the rolls or bringing them in on trucks on the same floor level as the reel is entirely eliminated and that they are placed ready for loading in a space not obstructed by reels or other mechanism. This facilitates the loading of the rolls where there is insucient room at the side of the press for the rolls to be brought in in the usual manner.

Although we have illustrated and described only one forrn of the invention we are aware of the fact that modications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore, we do not wish to be limited in this respect otherwise than as set forth in the claims, but what we claim is:-

l. In a reel loading device, the combination with a reel for supporting web rolls provided with chucks for holding the rolls at their centers, of a cradle located below .the reel and having a depression for receiving a web roll, said ydepression being of slightly larger radius than the roll, a pair or nuts integrally connected with the cradle, a pair of screws passing through said nuts, .said screws being rotatable but otherwise located in xed position, whereby the turning of said screws will raise or lower the cradle, said screws passing substantially through the axes of the chucks on which the new web roll is to be located, and means for turning the screws simultaneously, whereby a roll can be raised by the screws to such a position that its center is co-axial with the axis of said chucks on the reel and the roll can be moved in the cradle to bring the center thereof into exactly the right position.

2. In a reel loading device, the combination with a reel for supporting web rolls adapted to be turned to bring the web rolls to different positions and provided with chucks for holding the rolls at their centers, of a cradle located at a `material distance below the reel and having a depression for receiving a web roll, a pair of nuts integrally connected with the cradle, a pair of screws ypassing through said nuts, said screws being rotatable but otherwise located in fixed position, whereby the turning of said screws will raise or lower the cradle, said screws passing substantially through the axes of the chucks on which the new web roll is to be located, and means for turning the screws simultaneously and for oscillatingthem, whereby a roll can be raised by the screws to such a position that its center is substantially co-axial with the axis of said chucks and the reel can be turned to .bring the chucks .into substantially the proper position and the cradle can be jogged up and down to bring the center of the roll into exactly the right position.
